Based on your description of the accident (thankfully it wasn't more severe to you or the bike), especially the lack of contact save the left sided ground landing, the odds are quite favorable that the carbon fork is unharmed structurally. A carbon composite can become weakened it if it's taken an impact which has broken the resin bond between fibres and thisfibers. This delamination results in weakened areas. This delamination spreads as welldelamination can spread out from the area initially damaged.

I'll defer to others here to elucidate the physics involved, but generally, the braking forces acting upon the fork are concentrated along the forward, leading edge and the backside, trailing edge of the fork and it's steerer tube. The emergency braking resulted in enough force to momentarily defeat gravity and begin a loaded rotation around the hub/rotor area, but carbon composite forks are designed (significantly, by direction of weave and thickness of laminate at fore and aft edges) to withstand far greater force than this. The absence of plasticity in carbon fiber means the fork---all carbon aspects of the fork if not full carbon--is in no way deformed from the powerful braking episode. The presence of a thru axle was helpful to the scenario, allowing force to be spread over a larger area as well as diminishing potentially damaging twisting forces upon the fork.

Regarding the rotor: take it off and have it trued. Reinstall and then go about the simple, straight forward process of realigning the caliper. Here's a Park Tool article that covers the mechanical details that need to be taken to do those jobs. A note about the caliper: certainly something significant could have affected the caliper because of the extreme braking instance but it's much more likely to be unharmed. Probably designed to tolerate far greater forces, the caliper wouldn't even wear out much faster if every brake activation generated the degree of force experienced here.

Finally, I offer you this q&a from this site that may guide you to the next steps to take in order to build confidence that all is well.
